For er9x, go to http://code.google.com/p/er9x/source/br ... vn%2Ftrunk and read the file 'changelog.txt'. This has a summary of the changes done for each commit.
Only very occasionally does a revision have a real problem that upsets things. You should be safe to get the latest revision. If there is a problem, you should be able to revert to a previous revision until it is fixed. Always worth saving your EEPROM before flashing a new revision, then, if you need to go back, you have both the flash and the EEPROM available to put everything back as it was.

Ultrafire in the transmitter
Where to find parts? Refactoring your entire transmitter, new cases? Sticks etc..
